[Current situation and problems associated with inactivation of microorganisms in water using copper].

Objectives: The current situation and problems associated with inactivation of microorganisms in water using copper were elucidated.

Methods: A literature review was conducted regarding the history and mechanisms of inactivation technology using copper, the variety of microorganisms shown to be inactivated by these methods in previous experiments, and the efficacy of such technologies for the inactivation of microorganisms in water.

Results: The use of copper for inactivation of microorganisms has a long history.
